- EncroChat service as a “user-friendly secure instant messaging client” with “guaranteed security” ?
- GrapheneOS is an Android-based, security-hardened, privacy focused mobile operating system.
- Tools to secure sim card ?
I dont think you know what our distribution is.
if you need a secure communication system please use either signal.org or other end-to-end encrypted systems like matrix.org (riot.im is an awesome client for the matrix protocol) and xmpp with otr or gpg cryptography (conversation.org is my favorite mobile xmpp client)
in the near future the berty team should release their awesome serverless chat system based on ipfs (https://berty.tech) but they are still work in progress
